Abstract

The paper is about the Nanotechnology and its engineering applications in the field of biomedical applications and their health problems. Nanotechnology is engineering at the molecular (groups of atoms) level. It is the collective term for a range of technologies, techniques and processes that involve the manipulation of matter at the smallest scale (from 1 to 100 manometers — 1/10,000th the thickness of a human hair). Nanotechnology is an extremely powerful emerging technology, which is expected to have a substantial impact on medical technology now and in the future. The potential impact of novel nonmedical applications on disease diagnosis, therapy, and prevention is foreseen to change health care in a fundamental way. Furthermore, therapeutic selection can increasingly be tailored to each patient’s profile. In particular, relevant applications the surgery, cancer diagnosis and therapy, bio detection of disease markers, molecular imaging, implant technology, tissue engineering, and devices for drug, protein, gene and radionuclide delivery. Many medical nanotechnology applications are still in their infancy. However, an increasing number of products is currently under clinical investigation and some products are already commercially available, such as surgical blades and suture needles, contrast-enhancing agents for magnetic resonance imaging, bone replacement materials, wound dressings, anti-microbial textiles, chips for in vitro molecular diagnostics, micro cantilevers, and micro needles.
